Hewlett-PackardCorporate Overview

• Our partnership with Ariba started in 1999 with the Ariba Buyer application.• Ariba Downstream is HP’s standard procurement application for ordering

non-production goods and services. It automates the requisition, approval, purchase and payment processes and enables employees to easily purchase the items they need through an intuitive and efficient user interface. It is one component of the Global Procurement Requisition-to-Payment (R2P) platform which strengthens compliance and controls, thereby decreasing procurement costs.

• Ariba Upstream delivers an integrated set of tools and processes that enable procurement professionals to identify savings opportunities, utilize advanced sourcing strategies, manage contracts and monitor compliance to achieve HP business goals. We have customized heavily on Contracts Management, Sourcing, Supplier Performance Manager, and Analysis (Reporting).

HP is highly dependent on the Performance of the Application given our requirements and usability across the globe.

Our Application is considered as Mission critical and high availability is a basic requirement.

We have come across major performance issues and also stabilized them in the shortest of the time.

Our performance concerns –¨ Stuck Orders and Requisitions¨ User Folder Items¨ User navigation between Screens¨ System hangs - Progress bar hangs¨ Supplier Bidding¨ Master Data loads and CDS pulls¨ Workflow issues¨ Database locks¨ Reports timeout


Performance and Scalability• Solution for Performance issues• Increased Task Runner Nodes• Database tuning• Optimization of Queries• Changed Search logic• Memory Tuning• Rolling Restart of Nodes and Weekly Full Restart• Indexes and db stats• Controlled User Permissions• Reduced Folder Items• Performance testing is performed on each release using loadRunner and

WinRunner • Any performance issues that occur between releases are addressed

with tuning.



• Scalability is a very important aspect to maintain the consistent performance of the application.

• Our automated monitors track the application metrics to avoid system downtime and sends alerts to support team.

• We have exponential growth in users and transactions over years. In order to provide a good performance, we have increased our server’s capacity and increased the nodes.

• HP has high standards for Technology and Hardware and to keep up to the pace of these standards we have to keep moving to latest Hardware and technology which has helped us to monitor the scalability factor frequently.
